Swifty Corporation began using dollar-value LIFO for costing its inventory two years ago. The ending inventory for the past two years in end-of-year dollars was $281000 and $444000 and the year-end price indices were 1.0 and 1.3, respectively. Assuming the current inventory at end of year prices equals $646000 and the index for the current year is 1.35, what is the ending inventory using dollar-value LIFO? (Round intermediate calculations and final answer to O decimal places, e.g. 10,000.) $510874. $537574. $548374. O $544624
